Abstract
The invention discloses an iron-based amorphous alloy used for printing and dying wastewater treatment. The iron-based amorphous alloy is characterized in that the atom percent of iron element is 62%-77% and the preparation method of the alloy comprises the following steps: (1) selecting raw materials according to the proportion of the target alloy, and placing the raw materials of the amorphous alloy in the inner tube of a quartz tube; (2) placing anhydrous silicon oxide outside the inner tube of the quartz tube, taking out the inner tube to ensure that silicon oxide is covered around the raw material cylindrical side, covering the upper part of the raw materials, and turning the quartz tube upside down to ensure that the bottom is covered with boron oxide; and (3) vacuumizing the quartz tube, heating at 1350-1580 DEG C to melt, and then placing the product in water rapidly to quench and obtain the finished product. The invention also discloses mixed use of a treatment agent containing the iron-based amorphous alloy and other amorphous materials. By adopting the iron-based amorphous alloy and the treatment agent, the printing and dying wastewater treatment field is expanded and the treatment depth is obviously increased.
Description
Technical field
The present invention relates to a kind of treatment agent that is used for treatment of dyeing wastewater, especially Fe-based amorphous alloy and or other non-crystaline amorphous metal.
Background technology
At present; Techniques of Dyeing Wastewater Treatment mainly comprises physisorphtion, chemical flocculation, membrane separation process, chemical oxidization method, biological degradation method etc.; Existing these different treatment technology respectively have its relative merits and suitability; Maximum shortcoming is exactly the pollution destruction to environment, does not reach the essence of pollution treatment, because produced the pollution of the treatment agent of new introducing.
Reduced iron powder and cast iron scrap also are applied in the processing of dyeing waste water, but after the traditional reduction iron powder is handled, need the very long treatment time just can reach the standard of subsequent disposal; And this method need just can have tangible effect in certain pH value scope, and this just need carry out the adjustment of pH value to large batch of dyeing waste water, and is very inconvenient for practical application.
Iron exists with atomic state, and what kept that Zero-valent Iron itself has removes the look function, and has Fe-based amorphous advantage concurrently, and be a kind ofly has the dyeing waste water of using value to remove the look material very much.
Simultaneously, for existing Fe-based amorphous, it is only general has provided processing waste water, but the moity of non-crystaline amorphous metal is not carried out refinement, and the technology of existing preparation amorphous is too complicated, is unfavorable for enlarging and produces, and reduces cost.
The more important thing is existing all is the processing of simplification, does not reach very well effect, and iron-based is responsive for the influence of pH value, is unfavorable for wastewater treatment widely.
Summary of the invention
To the deficiency of prior art, one of the object of the invention be to provide a kind of new Fe-based amorphous alloy treatment of dyeing and printing method and make the method for this Fe-based amorphous alloy.
The prepared a kind of Fe-based amorphous alloy that is used for treatment of dyeing wastewater of the present invention, the atomic percent of ferro element is between 62%～77%.
Also contain other in the said Fe-based amorphous alloy and add element: cobalt, boron, phosphorus, Hf, Ni, Nb, Ga, Mo, C, Y, Zr, W, Cr or REE or and composition thereof.
Described REE is: more than one among Pr, Sm, Tb, Dy, Nd or the Gd.
Described non-crystaline amorphous metal is middle iron atom and the ratio of cobalt atom is 5: 1～7: 1, or the ratio of iron atom and nickle atom is 3: 1～5: 1

The described preparation method who is used for the Fe-based amorphous alloy of treatment of dyeing wastewater comprises the steps: (1) according to the selected raw material of the proportioning of target alloy, and the raw material of non-crystaline amorphous metal is placed Guan Guanzhong in the silica tube; (2) dry oxidation silicon is put into outside the silica tube pipe, pipe makes silicon oxide be coated on around the raw material cylindrical sides in extracting, and raw material top is covered; Be inverted silica tube; Make also capping oxidation boron of its bottom, (3) vacuumize silica tube, and heating makes its fusion under 1350-1580 ℃; Move into quenching-in water after the fusion rapidly, promptly get product.
One of outstanding advantage of the present invention and beneficial effect are, a kind of non-crystaline amorphous metal that is used for wastewater treatment is provided, and its treatment effect is superior to general non-crystaline amorphous metal; Two of outstanding advantage of the present invention has been to confirm the crucial several atomic ratios of influence in the non-crystaline amorphous metal, this specific than the time, it is to playing the best use of with the decolouring reducing power; Three of outstanding advantage also is to provide and being used of other non-crystaline amorphous metal, and has improved in the processing speed of acid waste water and the expansion of alkali solution and has used.
